I guess it depends on how far away is the
closest thing that will reflect light. If
you've got the Flood-Cam looking kind-of far-
out, like into a field where there may not
be anything to reflect much light, you won't
see anything...
I've got a Flood-Cam on one end of my front
porch which is the same length as the front
of the house, say 40 feet. When it comes-on
at night, the other end of the porch hardly
gets sufficient lighting from the one
floodlight to see the end of the porch.
The same went for my tool shed in the back
yard. I've got a flood-Cam on a corner of
the house watching the shed which is about
20-25 feet away. The one flood wasn't realy
enough light to get a good image of the
shed, so I installed a regular flood on a
stanchion above the shed door that has an X-
10 switch addressed the same as the Flood-
Cam. With the combined 600 watts worth of
light, it is plenty. I hope this is of help.
